Dr. Frank Poole

When walking outside to repair a fault that the computer HAL claimed to see, he was hit by a pod arm controlled by HAL, which also cut off his air hose, sending him adrift. As Poole drifts away from the ship, he tries in panic to attract the air hose again, but eventually runs out of air and dies of suffocation.

His body drifts away in space, but Dave later finds it and brings it back to the spaceship. However, after HAL refuses to let him in, he enters through the emergency exit and abondons Frank's body, most likely sending it deep into space.
